T all whom it may concern:

Be it known that I, FRITZ Dr'iizR, a citizen of the German Empire, and resident of Karlsruhe, Baden, Germany, have inventedc'ertain new and useful bureting Apparatus for Explosion-Engines,

of which the following is a specification.

The object of the invention is tov provide a carbureting apparatus which will insure a thorough mixing of air and hydrocarbon,

whereby it is possible to obtain practically perfect and complete combustion and avoid wastlng hydrocarbon.

" The apparatus includes a chamber to which The accompanying drawing-illustrates an apparatus constructed in accordance with the invention.

It is amatter of indifference in, which way the apparatus is connected with the-motor. On the drawing the motor is arranged on the left of the apparatus.

The motor 1 is provided with the sockets 2 and 3, the gaseous mixture being introduced through the socket 2, while the exhaust' ipe of the motor is supposed to be at 3. 0th

sockets are connected with a so-called evaporator 4. The latter is divided by partitionwalls 6, 7 into several chambers in a manner that the'inner space 7 is connected through a tube 8 with the entrance-socket 2, while; the exhaust-pipe 3 is connected through an opening '9 with the evaporator 4:, and the pipe 10 at the lower part of the evaporator forms the outlet into the open air. The latter may, the

same as all similar conduits, have its outlet above the roof f the engine-house. The

evaporator 4 possesses moreover a ing-pipe 10. To the latter is connected-an apparatus 11 by means .of the socket 12 This apparatus carries in the interior a pipe 13 and has two groups of openings 14 and 15. The pot-shaped apparatus 11 is-closed by a hood 16 provided m a suitable place with an air-valve 17. The latter opens into the in- :5 terior and passes in a cross-piece 18 through Improvements in Car ,finely divided hydrocarbon mixed connectthe guide-rod 19, while a spring 20 continuously effects the closing of the valve. I

Around the o en ings 14 and 15 is arranged a turnable annu ar slide 21, which is likewise provided with openings 22, 23,

s 0nd with the aforesaid openings 14, 15. his annular slide is connected through the screw 35 with a lever 24 arranged on the out- I side of the hood 16 If the winged nut 25 of which correthe screw 35 is loosened the annular slide 21 can be turned to the left or right, a transverse slot in the hood 16 permitting such movement of the screw 35. In this way the openin s 14 and 15 can be fully or partly covere throu h the valve 17 be regulated, as re quired. In the middle of the hood is pro- ,vided a conduit 26, which projects into the interior in the middle of the hood and termi- The conduit 26 is con- 'nates in a nozzle 27 nected'to a fast running rotary pum 31. At I the bottom of thepot-shaped vesse 11' is inserted another conduit 28, which is connected with a branch conduit 29. A third con or closed and the admission of air 7o duit 30 connects both conduits 28 and 29 stwith the rotary pump 3 1 'The working is as follows: llf'the rotary pump is put into rotation it sucks the fluid ydro-carbon through the conduit 29, puts it under ressureand pressesit through the pi e,

26 to t e nozzle 27, where, as shown in t e drawing, it enters the ot-shaped apparatus" in an exceedingly fine y divi ed state. As

long-as the valve 17 is closed and no air passes into the interior of the vessel 1 1 the finely divided drops of hydrocarbon collect at the bottom of the vessel 11 and are suckedup there by I d conveyed into' the pipe 26.

the pump 31 an 'As soon as the inlet for the gas is opened in the motor the valve 17 opens itself and the with the air is drawn" towards the motor. ()nthis way the hydrocarbon through the evaporator, namely through the v chamber 32 and .the socket .8; But this chamber is heated bytheheat-of the exhaust-gases which enters into the evaporator through the socket 3 and effects the com-u plete asification of the hydrocarbon. If one v ve 17 should not be suflicient several of them may be arranged inthe hood 16.

There isstill to be noted that the vessel 1 1 engmes i) v N must, however, pass with its internal arrangement forms a reser adjacent its upper I What I claim as my invention and desire to secure by United States Letters Patent 1s:-

In a carbureter for explosive engines, the combination of a reservoir having therein a centrally arranged tube the lower end of which is above the bottom of the reservoir, and said tube being provided with apertures end, a'cap closing the up per end of the tube and formingan annular chamber about the apertured section thereof,

' an inwardly opening valve closing an air inlet in a wall of the cap, a hydrocarbon nozzle extending into the central tube, and an annular valve surrounding the tube within the cap and adapted to regulate the passage of air through the apertures in the tube, substantially as described. 1
